Techniques to enable firewall bypass for open mobile alliance device management server-initiated notifications in wireless networks

Abstract

An embodiment of the present invention provides a method, comprising enabling firewall bypass for open mobile alliance device management (OMA DM) server-initiated notifications in WiMAX wireless networks by requiring that a certain OMA DM packet is captured by a WiMAX modem associated with a OMA DM client and routed via a predetermined driver interface.

1 . A method, comprising:
 enabling firewall bypass for open mobile alliance device management (OMA DM) server-initiated notifications in WiMAX wireless networks by requiring that a certain OMA DM packet is captured by a WiMAX modem associated with a OMA DM client and routed via a predetermined driver interface.   
   
   
       2 . The method of  claim 1 , wherein said OMA DM packet is an IP packet. 
   
   
       3 . The method of  claim 1 , wherein said predetermiend driver interface is the IoCTL WiMAX driver interface. 
   
   
       4 . The method of  claim 1 , wherein said OMA DM server initiates connection with said OMA DM client by sending a UDP packet to the OMA DM client inside a wireless device. 
   
   
       5 . The method of  claim 4 , wherein said OMA DM packet is transferred over WiMAX RF into a WiMAX modem, and through said wireless device OS's IP stack delivered to an application of said OMA DM client. 
   
   
       6 . The method of  claim 5 , wherein said WiMAX modem or its related drivers monitors incoming UDP packets and intercepts said OMA DM packets instead or in addition to submitting bootstrap/package 0 packets to a normal IP stack, said WiMAX modem also sends the information across the proprietary driver's IOCTL control interface into a WiMAX control stack and from there to said OMA DM client application. 
   
   
       7 . The method of  claim 6 , wherein the interception of said packets is by port number or by pattern matching the data of the UDP packet or by comparing the UDP source IP address to a pre-set IP address of said OMA DM server which the OMA DM client pre-sets in the modem. 
   
   
       8 . A system, comprising:
 an OMA DM server; and   a wireless client operable to communicate with said OMA DM server over a WiMAX network, wherein said system enables firewall bypass for OMA DM server-initiated notifications in said WiMAX wireless networks by requiring that a certain OMA DM packet is captured by a WiMAX modem associated with said wireless client and routed via a predetermined driver interface.   
   
   
       9 . The system of  claim 8 , wherein said OMA DM packet is an IP packet. 
   
   
       10 . The system of  claim 8 , wherein said predetermiend driver interface is the IoCTL WiMAX driver interface. 
   
   
       11 . The system of  claim 8 , wherein said OMA DM server initiates connection with said OMA DM client by sending a UDP packet to the OMA DM client inside a wireless device. 
   
   
       12 . The system of  claim 11 , wherein said OMA DM packet is transferred over WiMAX RF into a WiMAX modem and through said wireless device OS's IP stack delivered to an application of said OMA DM client. 
   
   
       13 . The system of  claim 12 , wherein said WiMAX modem monitors incoming UDP packets and intercepts said OMA DM packets and instead or in addition to submitting bootstrap/package 0 packets to a normal IP stack, said WiMAX modem also sends the information across the proprietary driver's IoCTL control interface into the WiMAX control stack and from there to said OMA DM client application. 
   
   
       14 . The system of  claim 13 , wherein the interception of said packets is by port number or by pattern matching the data of the UDP packet or by comparing the UDP source IP address to a pre-set IP address of said OMA DM server which the OMA DM client pre-sets in the modem. 
   
   
       15 . A apparatus, comprising:
 a wireless device operable to communicate with a OMA DM server over a WiMAX network and capable of enabling firewall bypass for OMA DM server-initiated notifications in said WiMAX networks by requiring that a certain OMA DM packet is captured by a WiMAX modem associated with said wireless device and routed via a predetermined driver interface.   
   
   
       16 . The apparatus of  claim 15 , wherein said OMA DM packet is an IP packet. 
   
   
       17 . The apparatus of  claim 15 , wherein said predetermined driver interface is the IoCTL WiMAX driver interface. 
   
   
       18 . The apparatus of  claim 15 , wherein said OMA DM server initiates connection with said wireless device by sending a UDP packet to the wireless device. 
   
   
       19 . The apparatus of  claim 18 , wherein said OMA DM packet is transferred over WiMAX RF into said WiMAX modem, and through said wireless device OS's IP stack. 
   
   
       20 . The apparatus of  claim 19 , wherein said WiMAX modem monitors incoming UDP packets and intercepts said OMA DM packets and instead or in addition to submitting bootstrap/package 0 packets to a normal IP stack, said WiMAX modem also sends the information across the proprietary driver's IoCTL control interface into the WiMAX control stack and from there to said wireless client.
